RING COMPRESSOR.

Application filed June 6, 1925. Serial No. 35,323.

This invention relates to improvements in piston ring compressors and the like and contemplates the provision of a relatively fiat split ring having beveled inner walls or outwardly inclined inner walls which are adapted to engage and allow the piston rings upon a piston when so inserted within a cylinder to be so compressed and guided into the cylinder walls in order that the under sides of the piston rings will not engage the upper sides of the cylinders when so inserting the same therein.

Another object of my invention is the provision of an outwardly extending annular flange upon the bottom of the ring compressor and which is adapted to engage the upper side of the cylinder block around the respective cylinder in order that the same will be held against canting and guide the piston rings within the respective cylinders and preventing the distortion of the piston rings.

A further object of my invention is the provision of a pair of long and short end lugs, one of which is arranged upon the outer side of the ring compressor and in spaced relation to the split portions thereof while the longer end lug extends over and bridges the space between the split portion of the ring compressor and includes a thumb screw or the like passed through one of the end lugs and threaded into the other end lug in order that the ring compressor may be adjusted to fit various sizes of piston rings.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claim.

In the drawing Figure 1 is a side elevation of a piston shown partly arranged within a cylinder and showing the manner in which the piston rings may be guided within the cylinder walls of the block, parts of the device being broken away and shown in section.

Figure 2 is a top plan view of my invention.

Figure 3 is a fragmentary side elevation showing the adjusting means included thereon and in juxtaposition with the split portion thereof. 7

Referring to the drawing in detail, wherein like characters of reference denote corresponding parts, the reference character 10 indicates a relatively fiat split ring which is preferably outwardly inclined 'or obliquely disposed circumferentially thereof and which side of my ring compressor 10 in the act of guiding the piston rings 13 into the cylinder 14 and obviating the lower edges of the )iston rings 13 from engaging the upper e ges of the cylinder 14 and thus preventing the distortion of the rings.

In order that piston rings of smaller and larger sizes may be guidedwithin cylinders and the like with the use of a singular ring compressor 1 provide long and short end lugs 16 and 17 which are arranged adjacent the split portions of the ring compressor 10, the long end lug, as clearly illustrated in Figure 3 of the drawing, extends over the outer side of the ring compressor 10 and across the split portions thereof, and the threaded shank 18 of the thumb screw is passed through the lug 17 and threaded into the lug 16 in order that the ring compressor 10 may be contracted and expanded as the case may be in the process of fitting and compressing rings of various sizes.

The invention is susceptible of various changes in its form, porportions and minor details of construction, and the right is herein reserved to make such changes as properly fall within the scope of the appended claiml Having described my invention what is claimed is: V

A ring compressor consisting in a split ring having its wall diverging upwardly, an

annular flange extending entirely around the ably connecting the strips, one of said strips lower edge of said ring, said flange being bridgingthe open juncture of the ring at all designed to overlie the end of a cylinder and times to form a guiding means in the ad- 10 form a broad bearing support for the ring, justment of the ring.

5 and a means for adjusting the ring, In testimony whereof I afiix my signature.

said means including strips connected to the respective ends of the ring and a bolt adjust- BERTTIE M. COLEMAN.
